To all 'whom t may concern.'

Be it known that I, EDWIN A. PERKINS, a citizen of the United States, residing at 74-Mddletown Stret, Jamaica, Long lsland, in the county of Queens andState of New Yorkhave invented certain new and useful*Improvements in Spindles, of whichl ball bearings that would stand the commercial requirements.

Myspindle has solved these problems and combines two ball bearings in a self-balancing type of spindle, so that the spindle will do the required work in an eflicient manner over a long period of' time and with a great saving of power required.

Referring to the drawings Fig. 1 is a sectional view of my spindle. Fig. 2 is a perspective of the center shaft. Flg. 3 is a top plan view of the center shaft. Fig. 4 is a perspective of the bushing which supports the center shaft. Fig. 5 isa top plan view of the bushing.

In the drawing 6 is 'a base member, which is adapted to be rigidly secured to the rail ot the cotton spinning machine, and has an external threading 7 over which a j nut 8 -is adapted to be screwed for this purpose. The upper end of the base member is cut out to form a cylindrical cup 9, and said `cup member has an inturned cylindrical lip 10. There is also an oil filling member 11 on one side of said cup 9, which has a cap member 12 of usual construction. The base member 6 also has an internal longitudinal ing l5 and the boringil of thebase memrber 6, said flanges 19 being adapted to register between the internal longitudinal flanges 18 of the bushing 15. l

The segmental flanges 19 have ext-ended flanges 20 on which a ball bearing 21 of usual cage and inner` and outer race construction is adapted to rest.

The segmental flanges l19 also have outer threaded portions 22 at their upper ends, over which a nut 23 is adapted to screwthe ball lbearing 21 in position. l The center shaft 40 also has a shoulder 24 near its upper end, on which a second ball bearingI 25 of the same construction as 2l is adapted to rest, and the upper end of the center spindle is threaded at 26, over which a nut v .27 is adapted to be screwed, thereby holding the ball bearing 25 in position. The center 'shaft '40 also has a cylindrical boring 28 inwhich a wick is adapted to be placed.

A whirl 29 is adapted to fit over and rest on the ball bearings 21 and 25, and has a cylindrical lip 30 adapted to effect the closure of the cup 9 in co-operation with the lip 10. The whirl 29 also has a cylindrical face 31 against which the belt of the spinning -machine is adapted to contact in order `to drive the spindle. The whirl 29-also has an internal cylindrical. threading 32 at its upper end, into which a plug 33 having external threading 34 is adapted to be screwed; The plug 33 is bored at 35 so that a blade 36 can be driven therein to make a tight fitting. v

A s'the oil is poured into the fller'11 it will run down into the base of the boring 13, and as it contacts with the wick in the boring 28 will be carried by molecular action lto the top of the shaft, whence itwill be thrown off by the whirling of the base of the blade 36 contacting against the upper end of the wick and pass through the ball bearing 25 down to the ball bearing-21 on to a baile plate 37, which has holes therein to permit it to pass through into the cupA 9, whence it will pass through the hole 38 into the boring 13. This operation will continue until the oil is used up.

It is seen from the foregoing description that the whirl 29 carrying the blade 36 rotatesfreely on the ball bearings 21 and 25, and 'any slight variation from' the center by the cylindrical shaftf40 on which the bearings 21 and 25emecarried will be corrected by means of the dashpot formed in the base of the boring 1 3. which is lilled with oil,

combined with the fa't that the shaft -i-O-has just enough play between it and the hushing l5 up to the point of close contact with the whirl 29 to permit this.

l. In a spinning spindle a base member continuously lubricating said bearings.

2. In a spinning spindle a base member having lubricant containing means, a bush- 'ing mounted rigidly to said base, a selfbalancin bolster mounted in said bushing, a whirl aving a blade integral therewith and enlarged head and foot portions mount-- ed on said bolster by means of ball bearings in said head and foot portions, and means for continuously lubricating said bearings comprising a wick channel in said bolster and a wick therein, said blade base forming a linger running adjacent the upper portion of the wick channel.

3. In a spinning spindle, the combination of a rigidly secured base member having a longitudinal boring, a bushing rigidly secured to said base member supporting a self-balancing cylindrical bolster at its upper end, the lower end of said bolster swinging freely in oil in said boring which acts as a dash-pot, a whirl having enlarged head and foot portions carrying ball bearings therein,'supported by said bolster, a blade rigidly secured to said whirl, and means for continuously lubricatingk said bearings. all. In a spinning spindle, the combination of a rigidly secured base member having a longitudinal boring, a bushing vrigidly secured to said base member supporting a self-balancing cylindrical bolster at its 'upper end, the lower end of said bolster swinging freely in oil in said boring which acts as a dash-pot, a whirl having ball bearings, carried by said bolster and adapted to support the head and foot4 portions of said whirl, a blade rigidly secured to said whirl, and means for continuously lubricating said bearings comprising a wick channel in said bolster and a wick therein, said blade base forming a flinger running adjacent the upper portion of the wick channel.

5. In a spinning spindle, the combination of a rigidly secured base lmember having a longitudinal boring, a bushing rigidly secured to said base member, a self-balancing cylindrical bolster mounted 4in said bushing so that oil in the boring acts as a dashpot for said bolster, a whirl supported in enlarged head and foot portions thereof by ball bearings carried by said bolster, a blade rigidly secured to said Whirl in combination with means for continuously lubricating said bearings.

6. In a spinning spindle, the combination of a rigidly secured base member having a longitudinal boring, a bushing rigidly -secured to said basemember, a self-balancing cylindrical bolster mounted in said bushing so that oil in the boring acts as'a dashpot for said bolster, a whirl supported 1n the head and foot portions thereof by ball.

bearings carried by saidl bolster, a blade A the blade being formed as a dinger runni adjacent the upper portion of the wie channel. r

8. In a spinning spindle a base 'member having lubricant containing means, means for preventing agitation of saidlubricant, a bushing mounted rigidly to said base, a self-balancing bolster mounted in said bushing, a whirl having a blade integral therewith and enlarged head andfoot portions mounted on said bolster by means of ball bearings in said head and foot portions, and means for continuously lubricatingv said bearings.
